thenticated, the machine enables setting of the operation of the Overwrite All Data function.
When the machine is to be discarded, or use of a leased machine is terminated at the end of the leasing con-
tract, the Overwrite All Data function overwrites and erases all data saved in all spaces of the HDD. The func-
tion also resets all passwords saved in the NVRAM to factory settings, preventing leak of data. For details of 
items that are cleared by the Overwrite All Data function, see page 1-8.
The HDD Overwrite Method offers the choice of eight different modes, [Mode 1] through [Mode 8]. Overwrite 
All Data takes about less than one hour in [Mode 1] at the minimum and about 9 hours in [Mode 8] at the 
maximum.
